INTRODUCTION
Electronics without silicon is unbelievable.
Pure Silicon and Germanium are semiconductors . These were used widely for manufacturing of electronic components.
Disadvantages when used in power electronics application, such as:
1) bulk in size.
2) slow operating speed, etc.
What is Diamond chip…?
Diamond Chip or Carbon Chip is an Electronic Chip manufactured on a diamond structure Carbon wafer.
Diamond structural carbon is non conducting in nature.
To make it conducting, doping process is performed.
Boron-- as the p-type.
Nitrogen--as the n-type.
Carbon nano-tube (CNT)
CNT’s are allotropes of carbon with a cylindrical nanostructure.
CNT’s are Nano-dimensional tube made up of graphite layers.
Nanotubes have been constructed with length-to-diameter ratio of up to 28,000,000:1.
Applications of CNT’s
Interconnections inside the chip.
Carbon nanotube transistor (CNFET) manufacturing.
Molecular logic circuit.
Limitations of Diamond chip
Much more expensive than silicon.
Electricity cannot travel smoothly through diamond.
